Question

Which of the following statements about sugar alcohols is not true?

a. They contain no kcalories.
b. They can cause a laxative effect.
c. They are not actually alcohols or sugars.
d. They do not promote tooth decay.

Answer 1

Sugar alcohols do not promote tooth decay and can actually help prevent it.

Step-by-step explanation:

The statement 'They do not promote tooth decay' is not true about sugar alcohols. Sugar alcohols are commonly used as sweeteners in sugar-free products like toothpaste and gum, and they can actually reduce the risk of tooth decay. This is because sugar alcohols are not fermented by bacteria in the mouth, unlike regular sugars. As a result, they do not produce acids that can erode tooth enamel and cause cavities.

For example, xylitol, a popular sugar alcohol, has been shown to inhibit the growth of Streptococcus mutans, a harmful bacteria that contributes to tooth decay. Some studies have even found that xylitol-containing toothpaste is more effective at preventing cavities than fluoride-only toothpaste.

In summary, sugar alcohols do not promote tooth decay and can actually help prevent it.
